	Hello, first of all I must tell you that I do not belong to this
mailing list as of yet, so, please respond to me via brush@cse.unl.edu.
Thank you very much in advance!

	My problem is as follows: 

	I have added a variable named bens_variable to ksyms.c as follows: 

	extern int bens_variable=10; 

	I have then exported the variable in ksyms.c as follows: 

	EXPORT_SYMBOL(bens_variable); 

	I then recompiled the kernel as bzImage and everything went
perfectly fine. I then wrote a module for that particular kernel which
is simple and looks as follows: 

	#define MODULE
	#define __KERNEL__
	#include <linux/module.h>

	int init_module(void){
		printk(bens_variable); 
		return 0; 
	}
	
	void cleanup_module(void){
		printk("<1>Module Unloaded\n"); 
	}

	But, of course, whenever I try and compile the module to load it
using gcc it tells me that bens_variable is undefined - which makes sense,
however I don't see how I can compile this without typing in 

	extern int bens_variable; 

	again. How do I get my module to compile and print out the value
of bens_variable as defined within ksyms.c? 

	Again, please respond to me via brush@cse.unl.edu. Thanks again in
advance!!!
